Sexing plants

So I've grown a handful of regular seeds out and would like to know what would be the simplest way of determining the sex of the plants without putting the entire plant into flower. I read that putting clones in water under 12/12 would work but my plants don't seem to stay alive for more than a week in that condition and that wasn't enough time to determine sex. Do I need to just do a regular cloning in a medium and then go right to flower?

Read about monstercropping and flowering clones and then decide.

The method I have been using the past 6-8 months may not be fastest method, but has been working great for me. I take clones of each but use a aero cloned to get some roots, then I’ll put 8-10 X 3 inch rooted clones (the best from each “mother” plant) into a small 3 gallon (approx) rectangle tote... make sure you know the placement of each, then after giving them a day or 2 to get roots moving, I’ll flip to bloom and can sex every one within 2 weeks or so..

I use coco but this could be done with dirt or in DWC likely just as easily... after I sex them, I kill the clones and the males and have just my females left to clone out and switch and by this point they are usually a good size to transplant to the final container...

From seeds, I can usually take 2-4 clones of each within about 2.5 weeks, tho it varies a
bit, about 10-14 days to root, 2 days after transplant to single container, 10-14 day to sex... so usually I have my females separated ready take clones from and/or switch to bloom about 45-50 days from seed. At this point, the females are usually ready to be transplanted from their 1-3 gallon pots, into their final 5-7 gallon pots which they finish in, or larger to hang onto for mass cloning.

May not be the fastest way, but it works well for me. And since I am not a fan of monster cropping as it just takes a bit too much space and time to revert for my style, it works well and leaves me with my nice healthy, usually still symmetrically growing(seeds) females/mothers :)

Hope all goes well!! Happy growing :)

Thanks for that write up. It's made me realize that I should've planned this better from the start. I decided to take 2 clones from each plant, placed one in water and the other I'll be cloning normally. After 2 days, 2 of the clones in water began wilting heavily so likely they won't survive. I used rain water with a drop of nutes. I'm still unsure how people do that method with 100% success.

I don't want to monster crop either as I have way more veg space than flower and prefer to only place plants when they're meant to finish.

I ran into this problem myself. I tried using the cutting in water method. Sex was determined in a week. Problem is by the time the cutting showed sex, my plant was also showing sex shortly after.
Depending on strain and how long of a veg time you're running your plants may show sex themselves.

I've heard of people placing full plants in 12/12 for a few days and revegging but from my understanding this will put your plants behind by a week at least depending on how long it takes for them to reveg.

Myself, I've been going off of pre flowers this run.

If you wanna keep them in water to clone look at bubble cloners or aquium pump air stone stable temps of 78 degrees for your water
